On a different note, my C20J smokes on shutdown every time.....specifically out of the left exhaust stack. Any cause for concern?
How did you go about figuring this out? Our fuel is delivered by the same company as always, but could have switched where they got it from.

I believe the helicopter that we ended up changing the bearing on had this filter. The oil filter that rides behind the rubber engine oil tank in the aft cowling behind the hampster wheel, correct? Our other two ships do not have this filter.
